Based on part 1 of the study for partial environmental assessment of construction materials in mechanical engineering (Feig et al., 2015), the results will be translated in an example of use. The example shows two systems of skid conveyor, one out of steel, the other one out of hand wood veneer composites. Both skid conveyors are applicated
in the automotive industry (Eckardt et al., 2014). In order to assess their ecological benefits, the two systems are contrasted with each other. In order to investigate transparently the environmental impact of materials to the application, the categories of global warming potential and primary energy demand will be used. Both factors describe the sustainability and environmental friendliness most accurately. The comparison is performed for the life phase of production and is therefore only partially.
